Original application filed June 9. 190% Serial No. 211.859. Divided and this application filed February 10.1905. Serial No- 245119- a To all whom it may concern:

Be it known that 1, CHARLES ELLSWORTII ADAMSON, a citizen of the United States, residing at Marion, in the county of Grant and State of lndiana, have invented certain new and useful Improvements in Copy- Presses, of which the following is a specification, reference being had therein to the accompanying drawing.

' This invention relates to an improvement in copy presses and is a division of my application tiled June 9th, 1904,;tnd bearing Serial No. 211,859.

The object of the invention is the provision of a copy press, which is simple in construction and with which the copy being made is at all times in full view of the operator. v

A further object is the'provision of a copy press in which the copying paper is carried on a roll and cut oil before the copy is made, thereby permitting the copies to be made onloose sheets, the paper being cutof a length to suit each particular letter.

A further object is the provision of a copy press with which the letter can be given one or more impressions before removing the copy therefrom.

Other objects of the invention will be apparent from the detailed descriptiongiven herein and the claims appended hereto.

In the drawings wherein a preferable embodiment of my invention is shown and wherein like numerals of reference refer to corresponding parts in the several views, Figure is a perspective view of my improved copy press; Fig. l is a longitudinal section A of the same; Fig. 3 is a front elevation; Fig. 4

ls adetail sectional view showing one of the side rails and the platen, and Fig. spective view of the platen.

Referring now more particularly to the drawings, the frauicof myma'chine comprises the two side rails A, A, and the connecting end pieces 13,8. 'lhe side rails A, A, arc provided at their front ends with the elevated bearing lugs o, u, in which is journalcd a rubber copyim roller t, whichis provided with a crank (Y for operating the same.

Journalcd iu the side rails Adircctly below and parallel to the copying roller isa small metal bearing roller 1). The roller ll is so spaced from the rubber copying rollcr as to give a suitable impression to the platen l), which works therol ctwccu. The said platen 5 is a. per- Renewed July 26, 1907. Serial No. 385.686.

is made of thin metal having its side edges provided with the depending flanges e, which serve to strengthen the same. The flanges, 0, when the platen is secured in position between the copying roller C-and the supportin roller D lit snu lv a ainst theends of t 2) 7 D N D said supporting roller, thereby preventing any lateral movement of said platen during the operation of the machine. The rear end of the platen E is provided on opposite sides with laterally projecting lugs, e, which pr0- ject into the longitudinally disposed'slots a, formed in the inner sides of the side rails A, A, and serve to support the platen in a. horizontal position. The slots a areof such a length that the lugs e on the platen E will abut against the ends thereof before the front end of the platen has been drawn from between the rollers C and l thereby preventing the accidental displacement of the same during the operation of the machine. The rear end of the platen is beveled. elf to form a cutting edge 0, for apurposc to be hereinafter more particularly set forth.

Secured in the frame of the machine is a feed roll F, adapted to contain a supply of copying paper, a dampening roll G, mounted" adjacent the feed roll F. a water receptacle ll, partially "surrounding said dampening roll G, and a delivery roll I, mounted adja- I cent to and contacting with the dampening roll G. Inasmuch as these parts form he part of the present invention, but are fully described and claimed in my former application, of which this is a division, 1 will not give a detailed description of these parts herein. The copying paper extends from the feed roll F under the dampening roll G and over the delivery roll I.

The operation of my improved copy press is as follows: The crank t) is first operated to turn the copying roll, which will cause the platen to move rearwardly to the extent of its movement; the letter to be copied is then )laced on the. )laten with the rinted side l l l up; the delivery roll I. is then actuated to draw out as much of the dampcncd paper as is necessary to make the required co y; the dampened paper is then drawn baccwards against the cutting edge c of the platen E, 5 and then by pulling quickly to one side the sheet is cut off; the sheet thus obtained is then placed over the letter to be copied, and by turning the crank of the copying rollcr C the platen will be drawn between the rollers O and D to make the copy, the lugs e, on the rear end. of said platen serving to limit its forward movement. If desired the copy can then be removed from the. letter or by reversing the direction of the crank C the platen can be returned .to its normal position before removing the letter and copy.

I do not wish to limit myself to the precise form shown in the drawings as it is obvious that many minor changes might be made thereto without departing from the spirit of the invention.

Having thus described the invention what is .claimed as new and desiredto be obtained by Letters Patent is 1. In a copy press, .a frame, a pair of superposed rolls mounted in said frame, and a platen secured in said frame for longitudinal. movement between said rolls and in frictional engagement therewith, said platen liming provided .at its edges with flanges adapted to overlie the ends of one of said rolls to prevent lateral movement thereof.

2. In a copy press, a frame, a pair of superposedrolls ,mounted in said-frame, a platen secured in said frame for lon itudinal movement between said rolls, said platen be ing provided at its edges with flanges adapted to overlie the ends of one of said rolls, and with lugs adapted to engage with a ortion of the frame to limit the longitudinal movement of said platen.

3. In a copy press;'a frame comprising a pair of longitudirf ally slotted side rails, a supporting roll secured in said frame, a

platen resting upon said supporting roll and provided on opposite sides with lugs engaging the slots in the side rails, and a copying roller secured'insaid frame above said platen and in frictional engagement therewit 4. In a copy press, a frame, paper feeding and dampening mechanism mounted in said frame, a platen mounted for reciprocatory movement in said frame, and a copying roller mounted-in said frame and adapted to cooperate with said platen, one end of said platen being sharpened to form a cutting edge, as and for the purpose set forth.

5. In a copy press, a frame, a platen mounted to reciprocate therein, a copying roll mounted in said frame and in frictional engagementv with said. platen to impart a longitudinal movement thereto, means for I said rolls.

preventing lateral movement of said platen during its longitudinal movement,

and

means for limiting the longitudinal movement of said platen. a

6. In a copy press, a frame, comprising a pair of longitudinal slotted side rails, a supporting roll secured in saidframe, a platen supported on said supporting roll and providedat its edges with downwardly extending flanges adapted to fit snugly against the ends of said supporting roll to prevent lateral movement of the platen thereon and at its rear end with lugs engaging the slots in the side rails, and a copying roller secured in said frame above said platen.

, 7. In a copy press, a frame, a pair of superposed rolls mounted in said frame, a platen in frictional engagement with said rolls and longitudinally movable therebetween and means for maintaining said'platen ina horizontal position during the travel between 8. In a copy press a frame, asupporting rolljournaled therein, said frame bein provided with sup orting portions, a tudinally movab e platen adapted to rest on the supfporting rolls and the supporting por' tions 0 the frame and a copying roll ournaled in said frame above said laten and in frictional engagement therewith 9. In a copy press, a frame, a pair of superposed rolls mounted in said frame, and a platen in'frictional engagement with said rolls and longitudinallymovable 'therebe- CHARLES ELLSWOlt'll-l' ADAMSON.
